AI Technical Summary

Technical Problem

In existing technologies, screen brightness adjustment methods cannot focus on displaying the main subject that is being watched by the human eye in the displayed image, and the power consumption reduction effect is not ideal.

Method used

By determining the saliency parameters and fixation point parameters of the displayed image, the brightness of each area of ​​the screen is adjusted to bring the brightness of the subject being gazed at to a level suitable for the human eye, while reducing the brightness of subjects with lower saliency. A neural network model is used to train a model to determine the saliency and fixation point parameters for brightness adjustment.

Benefits of technology

It enables the adjustment of the brightness of the subject being viewed in the screen image to a brightness suitable for the human eye, improving the user experience while reducing device power consumption.

Abstract

This disclosure provides a screen display brightness adjustment method and apparatus, electronic device, and computer-readable storage medium, relating to the field of device control technology. The method includes: determining a salience parameter of a displayed image on a screen interface, the salience parameter describing the salience of each subject in the displayed image; determining a fixation point parameter where the current human eye's gaze falls on the current screen interface, the fixation point parameter representing the area of ​​the current human eye's gaze; determining brightness adjustment parameters for corresponding areas of each subject in the displayed image based on the salience parameter and the fixation point parameter; and adjusting the display brightness of each area on the screen interface according to the brightness adjustment parameters. This disclosure, by determining the salience of each subject in the displayed image and the area of ​​the human eye's gaze on the screen, and accordingly determining the brightness adjustment parameters, can adjust the brightness of the observed subject to a suitable brightness for the human eye while reducing the brightness of unnoticed subjects.
